enabled.d/ — default-enabled service list (build-time markers)
================================================================

The symlinks in this directory mark which services from ../services/
should be enabled by default on a fresh Hammerhead install.

Only the BASENAMES matter here; the targets are intentionally dangling
(they point at e.g. `../acpihpd.toml` which doesn't exist in the
source tree). The Makefile's install_enabled_d target reads the
basenames and writes REAL symlinks at install time, of the form:

    $(ROOT)/etc/zyginit/enabled.d/<name> -> ../services/<name>

…which is what zyginit actually consults at runtime. So:

* To add a service to the default-enabled set: create a symlink here
  with the service's name. Target doesn't matter (`ln -sf ../<x>.toml
  <name>` matches the existing convention).

* To remove from the default-enabled set: rm the symlink here.

* The actual service definition lives in ../services/<name>/ and is
  always installed regardless of whether it's enabled by default —
  enabled.d/ only controls the initial state. Admins can later
  `zygctl enable <name>` to flip the symlink in place on a running
  system.

See ../Makefile (target install_enabled_d) for the rewrite logic.
